Add an Abandoned Bunker Map with Dynamic Lighting Events

Add a map set in a hostile section of an abandoned bunker, illuminated by yellowish or white lights. The bunker was frequently used by gangs in the past and is now serving as a temporary base in enemy territory. Once the location is discovered, troops are sent inside because bombing the bunker is not an option due to the surrounding civilian city. The map could feature a dynamic lighting event where the power goes out for approximately 15 seconds before the bunker enters an emergency or alarm state, bathing the environment in red light. This event could occur when other maps transition to nighttime. The floors and walls could feature worn concrete, damp corridors, exposed pipes, and other textures similar to the provided references.
